Since the center pieces cannot be moved relatively to each other it's important to solve the edge pieces correctly in relation to each other. For example, when solving the white in our case- the green center piece is to the left of the red center piece, therefore the green-white edge piece should to be solved to the left of the red-white edge piece (see image).

###### The standard Rubik's cube has sides of about 2.2 in (5.7 cm) per square. Various other sizes have also been produced such as a 1.5 in (3.8 cm) mini cube, a 0.8 in (2 cm) key chain micro cube, and a 3.5 in (9 cm) giant cube. While the standard cube is a 3 × 3 × 3 segmentation other types have also been introduced. Some of the more interesting ones include the 2 × 2 × 2 cube, the 4 × 4 × 4 cube (called Rubik's Revenge) and the 5 × 5 × 5 cube. The shape has also been varied and puzzles in the form of a tetrahedral, a pyramid, and an octahedral are among types that were produced. The Rubik's cube also led to the development of game derivatives like the Rubik's cube puzzle and the Rub it cube eraser.

*Repeat the process. Turn back to your blue side and repeat the turns on opposite sides. Then, return once more to the red side and turn the opposite sides in opposite directions. And last, return once more to the blue side and turn the opposite sides in opposite directions. When you finish, you should have a staircase-like zig-zag across four sides of your Rubik’s cube.[4] Rubiks Build It Solve It Review*

Puzzle makers have been creating problems for people to solve for centuries. Some of the earliest puzzles date back to the time of the ancient Greeks and Romans. The Chinese have a ring puzzle that is thought to have been developed during the second century A.D. This was first described by Italian mathematician Girolamo Carolano (Cardan) in 1550. When the printing press was invented, complete books of mathematical and mechanical problems designed specifically for recreation were circulated. Rubix Building Products

*Since the center pieces cannot be moved relatively to each other it's important to solve the edge pieces correctly in relation to each other. For example, when solving the white in our case- the green center piece is to the left of the red center piece, therefore the green-white edge piece should to be solved to the left of the red-white edge piece (see image).*

*If there are no more edges left on the top layer, then they are probably either inserted in the right place but flipped, or inserted in the wrong place. To get an edge out of somewhere it shouldn't be, just insert one of the yellow edges into that slot. This should get the edge out and on the top layer, ready for you to use the above instructions to insert correctly.*

__Rubik's cube is a toy puzzle designed by Erno Rubik during the mid-1970s. It is a cube-shaped device made up of smaller cube pieces with six faces having differing colors. The primary method of manufacture involves injection molding of the various component pieces, then subsequent assembly, labeling, and packaging. The cube was extremely popular during the 1980s, and at its peak between 1980 and 1983, 200 million cubes were sold world wide. Today sales continue to be over 500,000 cubes sold world wide each year. Rubiks Build It Solve It Review__

^{The commercial cube is composed of six fixed cubes, eight movable cubes on the corners and 12 movable cubes on the edges. Each cube is one of six colors. The Rubik's cube has red, yellow, blue, green, white, and orange colors. In its solved state, each color is on only one face. When the cube is rotated, the edges and corners move and the cube becomes scrambled. The challenge of the puzzle is to restore each cube to its original position. The cube is extremely challenging because there are slightly more than 43 quintillion (4.3 × 10 19 ) possible arrangements, and only one solution. }

*The quality of the individual parts are also inspected just after exiting the mold. Since thousands of parts are made daily, a complete inspection would be difficult. Consequently, line inspectors may randomly check the plastic parts at fixed time intervals and check to ensure they meet size, shape, and consistency specifications. This sampling method provides a good indication of the quality of the overall Rubik's cube production run. Things that are looked for include deformed parts, improperly fitted parts and inappropriate labeling. While visual inspection is the primary test method employed, more rigorous measurements may also be performed. Measuring equipment is used to check the length, width, and thickness of each part. Typically, devices such as a vernier caliper, a micrometer, or a microscope are used. Just prior to putting a cube in the packaging it may be twisted to ensure that it holds together and is in proper working order. This can be done by hand or by a turning machine. If a toy is found to be defective it is placed aside to be reworked later.*

_{For decorative purposes, a colorant is typically added to the plastic. The pieces of a Rubik's cube are typically black. During production, colored stickers are put on the outside of the cube to denote the color of a side. The plastics that are used during production are supplied to the manufacturer in a pellet form complete with the filler and colorants. These pellets can then be loaded into the molding machines directly. }

Even in the manual it states that you will need to practice using trial and error. Personally, we have a feeling that people who like doing puzzles and working things out will enjoy this more. It is important that you have patience when it comes to building the Rubik’s Build It Solve It cube. However, once you get the hang of this you are going to feel pretty smart. And your friends will be really impressed because it takes a bit of effort to solve one of these cubes. If you would like to read our review on the d-fantix cyclone 3×3 – please click on the link.

If it comes to constructing the Rubik’s Cube, it’s not as difficult as it seems. In reality, it is going to take approximately fifteen minutes and the directions are simple to follow. If it comes to putting the coloured tiles, be sure to look closely at where you’re supposed to put them since in the event that you snap them in the incorrect location, you won’t have the ability to eliminate them. Yes, you will continue to have the ability to use this Rubik’s Cube, however you won’t be able to follow along with the documentation manual on solving the mystery.

_{The Rubik's cube appears to be made up of 26 smaller cubes. In its solved state, it has six faces, each made up of nine small square faces of the same color. While it appears that all of the small faces can be moved, only the corners and edges can actually move. The center cubes are each fixed and only rotate in place. When the cube is taken apart it can be seen that the center cubes are each connected by axles to an inner core. The corners and edges are not fixed to anything. This allows them to move around the center cubes. The cube maintains its shape because the corners and edges hold each other in place and are retained by the center cubes. Each piece has an internal tab that is retained by the center cubes and trapped by the surrounding pieces. These tabs are shaped to fit along a curved track that is created by the backs of the other pieces. The central cubes are fixed with a spring and rivet and retain all the surrounding pieces. The spring exerts just the right pressure to hold all the pieces in place while giving enough flexibility for a smooth and forgiving function. Rubiks Build It Solve It }
